LANNER TRETHELLAN SW 73 NW 9/224 East Trethellan Farmhouse and attached outbuildings

II Farmhouse, now house. Probably late C17 or early C18, but incorporating some earlier fabric; altered, and currently under restoration. Coursed squared granite and uncoursed granite rubble, slate roof, brick chimneys. T-plan formed by single-depth 2-unit main range with rear stair-turret. Two storeys and 5 bays, symmetrical; unusual masonry consisting of roughly-squared blocks of granite varying in size and shape but laid to a regular pattern, with some very large blocks forming the base of the wall to the right of the door; central doorway and square windows arranged very regularly, all with splayed voussoirs, the doorway with a 6-panel door which has a long strap hinge on the bottom rail, and the windows now re-furnished with 16-pane sashes. Rebuilt gable chimneys. Lean-to kitchen attached at left end; outbuilding continued to the right (see below). Rear: the stair-turret and the wall to the left are of uncoursed rubble with large quoins, but the wall to the right matches the masonry of the front (except for lean-to addition at ground floor); window in stair-turret like those at the front, doorway to left, small window at 1st floor to right. Interior: large rectangular fireplace in 1st bay with massive jambs and lintel, and integral bread oven, stone-flagged floors (current restoration of bead-moulded beams, panelled doors and partitions, and staircase, copies details of orginals or fragments of them found on site). The attached outbuildings consist of a short range continued to the right and a long projecting wing, all 2-storeyed and of uncoursed granite rubble with quoins and corrugated sheet roofs; the continuation (which was formerly a mill water-powered through the rear wall) is of 3 bays, symmetrical, with central doorways on both floors and altered windows; the wing has irregular openings including 4 doorways (the 3rd a reduced wagon entrance with a long granite lintel), a window between the 1st and 2nd, and 2 small windows above. Hipped roof. Lean-to addition at end.
